UI-Test: a model-based framework for visual UI testing– qualitative and quantitative evaluation
(Springer, 2022) Parra González, Luis Otto; Alba Sarango, Bryan Andrés; Granda Juca, María Fernanda
During the testing stage in the software development life cycle, developers can take advantage of combining the requirements specification with the testing specification. This will allow the specification of the tests to require less manual effort, since, they can be defined or generated automatically from the require-ments specification. The requirements specification will thus be based on a more structured language, gaining in quality and reducing ambiguity, incon-sistency, and inaccuracy. In this research work, the UI-Test model-based meth-odological framework and its tool support are proposed. Both of these can gen-erate evidence based on the specification of agile user stories that are used in the validation of the functional requirements that must be included in the final version of the user interfaces of the developed software. Our proposal makes use of two model transformations to obtain the test scripts from user stories that will be applied in the process using SikuliX for automated visual UI testing. The results of the empirical evaluation of the effectiveness and user experience of the framework and its tool support suggest that the UI-Test tool can benefit testers by confirming that the actions proposed in the user stories can be run on the UIs.
How do negative emotions influence on the conceptual models verification?: a live study proposal
(Association for Computing Machinery, Inc, 2020) Mayhua Quispe, Angela; Suni Lopez, Franci; Granda Juca, María Fernanda; Condori Fernández, Nelly
The present live study is proposed with the objective of investigating the influence of negative emotions (i.e., stress) in the efficiency for verifying conceptual models. To conduct this study, we use a Model-driven Testing tool, named CoSTest, and our own version of stress detector within a competition setting. The experiment design, overview of the empirical procedure, instrumentation and potential threats are presented in the proposal.

CoSTest: a tool for validation of requirements at model level
(Institute of Electrical and Electronics Engineers, 2017) Granda Juca, María Fernanda; Condori Fernandez, Nelly; Pastor López, Oscar; Vos, Tanja Ernestina; Granda Juca, María Fernanda
We present CoSTest, a tool that supports the validation of Conceptual Schemas by using testing. The tool implements techniques for transforming instantiations from a Requirements Model into test case implementations by supporting a Model-driven architecture.
Mutation operators for UML class diagrams
(Springer, Cham, 2016) Granda Juca, María Fernanda; Condori Fernandez, Nelly; Vos, Tanja Ernestina; Pastor López, Oscar; Granda Juca, María Fernanda
Mutation Testing is a well-established technique for assessing the quality of test cases by checking how well they detect faults injected into a software artefact (mutant). Using this technique, the most critical activity is the adequate design of mutation operators so that they reflect typical defects of the artefact under test. This paper presents the design of a set of mutation operators for Conceptual Schemas (CS) based on UML Class Diagrams (CD). In this paper, the operators are defined in accordance with an existing defects classification for UML CS and relevant elements identified from the UML-CD meta-model. The operators are subsequently used to generate first order mutants for a CS under test. Finally, in order to analyse the usefulness of the mutation operators, we measure some basic characteristics of mutation operators with three different CSs under test.
Exploring Perspectives of Students on Using Mobile Apps to Improve English Vocabulary Through Youtube Videos: A Comparative Study
(Science and Technology Publications, Lda, 2024) Granda Juca, María Fernanda; Parra González, Luis Otto; Reinozo Trelles, Edisson Santiago; Parra González, Luis Otto
Currently, in countries where the mother tongue is not English language, globalization brings a very important requirement related with level of English since it facilitates communication in any area, be it, business, education, tourism, and so on. People need to have a good mastery of the English language, however, if the mother tongue is different from English, dominating the English language can become a very serious problem. Under these circumstances, in countries where the mother tongue is not English, educational institutions have included meaningful learning of English as a second language in their curriculum for many years. Vocabulary is one of the essential components of any language and it is required get a good level in order to have success in the process of teaching/learning of the English. Spaced repetition has been widely implemented and examined in mobile-assisted vocabulary learning as an important learning strategy. In this context, the purpose of this comparative study was to investigate and compare university students’ perspectives utilizing two mobile apps to improve English vocabulary in the Language Department at University of Cuenca (Ecuador): the first application is Slango and the second was chosen applying multi-criteria decision making of a set of mobile apps with similar features than Slango. Therefore, we did a comparative evaluation of the two mobile apps in order to evaluate usability by using SUS questionnaire and desirability by using Microsoft Desirability Test. Results show that Slango has similar features as ReadLang (the second app to compare) when it is used to improve student English vocabulary using YouTube videos.
Evaluating Extended Reality Application for a Virtual Museum. Case Study: Remigio Crespo Museum.
(Institute of Electrical and Electronics Engineers Inc., 2023) Parra Gonzalez, Luis Otto; Barreto Paredes, Christian Fabian; Agudo Guiracocha, Dayana Isabel; Granda Juca, María Fernanda
The COVID-19 pandemic was the main reason why many organisations decided to include information and communication technologies in their processes to allow them to continue with their activities, be it providing services to users (food, medicine, etc.), training/education or disseminating culture. In the field of culture, some museums incorporated technology into their operating environment, moving from face-to-face visits to virtual visits. However, in many museums, the lack of apps designed to solve the problem of virtual visits caused some to stop receiving visitors during the pandemic. In this context, this paper describes the development of an application with a user-centred design that incorporates extended reality to allow virtual visits to the Remigio Crespo Museum in the city of Cuenca (Ecuador). The evaluation carried out to verify the application's usability and learnability is also included. The results obtained indicate that users/visitors found the application usable and easy to learn
Analyzing emotions in conceptual models verification tasks performed in online contests
(Institute of Electrical and Electronics Engineers Inc., 2021) Mayhua Quispe, Angela; Suni Lopez, Franci; Condori Fernandez, Nelly; Granda Juca, María Fernanda
Emotion research in the area of software engineering has gained significant attention. Mostly this research has been focused on understanding the role of emotions in software programming carried out within collaborative software development environments. With the purpose of providing more evidence on emotion research in the early stages of the software life cycle, in this paper, we report the results of a live study conducted in competitive conditions. The main objective of the study is to analyze the emotions expressed by competitors when performing verification tasks with the support of CoSTest, a model-driven testing tool. Our results show that participants tend to experience more positive emotions (e.g., attentive, alert, active) than negative emotions (upset, hostile, afraid) when verification tasks are performed in an online contest.
Using ALF within the CoSTest process for validation of UML-based conceptual schema
(CEUR-WS, 2017) Granda Juca, María Fernanda; Condori Fernández, Nelly; Vos, Tanja Ernestina; Granda Juca, María Fernanda
The Unified Modelling Language (UML) is widely used for modelling software systems and its integration with executable languages, such as the Action Language for Foundational UML (ALF), provides a bridge between the graphical specification techniques used by mainstream software engineers and the precise analysis and validation techniques essential for the model-driven development of information systems. As far as we know, the idea of transforming Conceptual Schemas (CS) based on UML Class Diagrams into ALF to execute systematic ALF-based test cases against these CSs and to report defects by checking logs has not been explored to date. In this paper, we use ALF to create a testing environment to validate requirements and verify some system properties at the CS level. We also report on some of the implementation details and design decisions of our proof-of-concept tool, as well as its limitations and possible use scenarios.
